I will def confirm this. we have downed him before after figuring out how it works on this server but its a little off when compared to retail. it seems to be a problem with some poison explosion zones near the alter having a greater than intended range with splash damage extending into position 4 from position 3 when it goes off. I know personally I have a handful of wipes where I was simply one shotted by the poison explosion when I was a minimum of 5 yards away from the exploding zone and still running away from it... and I have a very good connection usually 70-100msec. Combine this with an explosion time roughly .25-.50 seconds faster than retail and it presents a situation where it may seem impossible, this does not even include connect/server lag which cant be helped. This encounter needs to be looked at, it presents a situation where exploiting may be the only way to progress past him for some groups I can personally say that everytime my raid goes there I hear whispers saying "lets do it this way or that way" usually involving clear exploits around heigans encounter mechanics. And, yes gro I am quite aware MYM has beaten him. I beleive the GM's noticed that as well, several times.
